Have a look at this thread @Kurisu

Tools for software diagrams

I need to draw/build some diagrams for my master’s thesis and I tried using Visio 2016 but I didn’t really like the way the program works and how the diagrams look. I always see these conference talks and presentations where people show really nice diagrams of software data flows and architectures so I was wondering if anyone has suggestions of tools to do this kind of work?

Is that the sort of thing you meant?
